a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

These are the thing that we can see with electron Microscope and cant see with light microscope are Endoplasmic Reticulum‚ Ribosome‚ and Lisosomes. 6 Endoplasmic Reticulum is an original that is responsible for creation of protein and lipid through the body Ribosomes are organelles that occurred inside the cell which is responsible for collecting the proteins from the cell.

body. It contains the nucleus‚ which is in general terms the control center of the cell and contains the genetic material of the cell (Boeree). It also contains cytosol‚ a nucleolus‚ a Golgi apparatus‚ ribosomes‚ mitochondria‚ and a rough endoplasmic reticulum (Cardoso). Cytosol is the watery liquid inside the cell that holds the cell together while the nucleolus is an organelle inside the nucleus that is responsible for ribosome synthesis. The Golgi apparatus is the structure that sorts‚ packages

Introduction Genetics: the science‚ which deals with the principles of heredity and variation. Heredity: transmission of characters from parents to their off spring. Variation: Differences for various characters among the individuals of the same species. Types of variation: 1. Environmental and 2. Hereditary 1. Heredity variation: Variation observed among the individuals of the same species due to difference in their genetic constitution is termed as heredity variation. 2. Environmental variation:

genetic material. The nucleus is surrounded by a nuclear envelope‚ made up of a double membrane which controls what enters and leaves the nucleus. The outer membrane of the nucleus is continuous with the membrane of the rough endoplasmic reticulum. The rough endoplasmic reticulum‚ also known as rough ER‚ is a membrane factory for the cell‚ it grows in place by adding membrane proteins and phospholipids to its own membrane (Campbell‚ 2015). It plays a major role in the production‚ processing and transportation

Chapter 2: Neurons and Glia 1. Introduction * Although there are many neurons in the human brain (about 100 billion)‚ glia outnumbers neurons by tenfold. 1:10 ratio. * Neurons are the most important cells for the unique functions of the brain. * Neurons sense changes in the environment‚ communicate these changes to other neurons‚ and command the body’s responses to these situations. * Glia‚ or glial cells‚ are thought to contribute to brain function mainly by insulating‚
